Kling AI has unveiled version 4.0 of its video generator, introducing several new capabilities. According to The Decoder, the updated tool now supports video clips of up to 30 seconds and accepts up to ten keyframe images as input. Additionally, the system's prompt comprehension has been expanded to handle up to 8,000 tokens.
New features in this release also include stereo audio support, multilingual lip sync, and a lighter Flash variant, enhancing both usability and output quality. These improvements mark a significant step forward from earlier versions such as Wan 3.0 and Seedance 2.5.
For Japanese markets, where multimedia content is increasingly integrated into marketing and entertainment, these advancements could offer innovative opportunities in FX, crypto, and equities sectors to leverage video-based communication tools.
